Hey I'm barely getting into using SketchUp to try and model some of my ship concepts for my novel. I love you work, but I was curious do you ever model the interior of the ships you create or only the exterior?

That's of course entirely up to you, but I'd like to see more maneuvering thrusters. You design those vehicles like aircraft, but that wouldn't work in space. Of course that approach is usually influenced by game physics - there aren't many games there that would try to use more or less realistic effects. Hell, a good bunch of games thrown realistic physics into the trash bin... just saying

It's called "reaction wheels", but it's only usable for a rotation along the center of mass. Problem with aircraft-like structures is that it's not the best thing for a space vessel. It radically changes the center of mass and makes atmospheric entry quite complicated as the trajectory has a very low margin of error (not to mention winged designes are not mass friendly). That's why NASA is going back to capsules - in case of problems it goes into ballistic mode (high g's) but can survive entry and it's lighter. So if you want to fly in space it's generally better to have vessel designed just for that, unless you go say from Earth to Moon frequently.
